VALVE-LIFTER.

Application filed June 16, 1914.

To all ti /mm. it may com-am:

Beit known that I, Gnonon G. THAU, a subject of the Emperor of Germany,and a resident of Evart, in the county of Osceola.

5 and State of Michigan, have invented a new and Improved Valve-Litter.which the following is a full, char, and exact description.

My invention relates to a device for re 1 moving or replacing the valvesof internal combustion engines, and generally termed a -valve lifter.

An object of my hi ention is to provide a device capable of thenecessary adjustments 115 to suit dillerent sized motors and differentsized valves.

A further object of the invention is to provide a lever for elicitingthe clamping or gripping of the valve, and to provide on the. 20 frameof the de ice a handle so situated relatively to the le er, that one manalone using the device can so manipulate it to remove or repl ce a alvcfrom a dismantled cylinder without tipping over the latter.

The invention 'l'uithermore has for its object, to improve. devices ofthe indicated character in various particulars to the end thateflicicncy in operation may he promoted, as well as simplicity inconstruction and 30 convenience of adiustment and control.

The invention will be particularly explained in the specific descriptionfollowing.

Reference is to be had to the accompanv inc drawings forming a. part ofthis spccification, in which similar characters of reference indicatecorrespond ng parts in all the views.

Figure 1 is a, side elevation of a valve lifter embodying my invention;Fig. 2 is a *0 section on the line 2-2 of Fig. 1; Fig. 3 is a detailcross section of the frame on the line 3 3 of Fig. 1; Fig. 4 is a detailvertical section on the line P4 of Fig. 1: and Fig. 5 is a detailhorizontal section on the line 55 45 of Fig. 1.

In constructing a. practical embodiment of the invention in accordancewith the illustrated example. the frame is provided, preferablyconsisting of a single I-loar. and

50 the same is formed at the upper end with a. handle 11. Adiacent tothe handle 11 at the upper end of the frame 10. and adjacent to thelower end of said frame, transverse sleeves 12, 13, are formedrespectively to 65 slidahly receive lateral arms 14. 15, equippedSpecification of Letters Patent.

with 'valveriamping means, as hereinafter descrihed. To adjustahly hindthe al'msl li, 1.3. in thrir respective sleeves, the latter are providedwith set screws 18, 19, the ends of which are received in depressions16, 17, in 60 "aid lateral arms.

.Yhc lower arm 15 is equipped With adjustable jaws to engage differentsized valve washers. The jaws 20 are each, pivoted by rivets ll orequivalent means to the 6,5 depressed outer end 22 of the arm 15, saiddepressed end being connected with the arm by a downwardly-extendingmember 23. The jaws 20 are provided with pins 241, which are received inarcuatc slots 25 in a 7.0 disk '26 secured by a pivot pin or rivet 27 t0the depressed end 22. A spring washer 29 eneath the head of the rivet 27gives the necessary friction between the parts. The washer 2' may beturned by means of ears 75 28 or equivalent meml'iers thereon. The jaws20 are provided with opposite angular recesses Q0. and with pins 30adjacent to the recesses. The recesses acc mmodate the rims of washersor collars on the valve stems, and with the pins 14. provision is madeto center collars. even large ones, and prevent the slipping of thedevice on the valve.

I have indicated a valve A in dotted lines 815 in Fig. 1 and a portionof a motor B. the letter a indicating the valve stem, a the spring. anda it washer or collar.

To engage the opposite end of the valve in gripping the same. a head 31is provided 90 on a vertically sliding presser bar or grip per har andisadapted to be operated by a lever 33 connected by a link 34 with thearm 14. said link being pivoted as at 35 to the lever 33. and at itsopposite end asat 9,5 36 to a bracket 37 on said arm 14. The bar 32 hasguided movement in a vertical sleeve 38 formed on the arm 14.Interengzaging elements are provided on the bar 32, and lever 33. whichpreferably consist of teeth 39 on said har. and a transverse pin 40 in.a vertical opening 33* of the lever. At the side of the opening 33opposite the pin 40, is a presser pin 41 under the influence of acompression spring 42. disposed in a housing 43 formed on the saidlever. as best shown in Fig. The arrangement is such that the pin 40 isnormally held maintained in posi tion to engage a tooth 39 of the bar32, but the pin 41 will yield to an upward move W) nu-nt of the lever topermit the pin to =lip ovcr thc tcclh 32 {)n a face of the clamp bar 3:,a vert cal crics oi ratchet tccth it i provided. a l'aptc l to heengaged by a pawl 4;) operating in a transverse opening .55 in theslcvvc I58, said pawl bcing carllQll on a rock shaft l6 provided with acrank hanvllrl7. and the shaft being under thc inlluoncc ot' a torsionspring; 455 which. normally ttlltlr to maintain the pawl in err gagmuontwith tho rack ll, so as to holtl the bar in tho drum-i ed position towhich it has hccn movrtl. by the lever 33.

By the lateral adjustment of the arms 14 the cleric/i! may be manic toconform to engincs anal motors of dillcvont sizes, and the differentsizcd valves arc accommodated by the described con'fitruction flfliiarrangement of the gripping jaws .20 and their appurtc nances.

Referring again to the handle 11, it is disposc-tl hcncath the lcvcr 33,and by reason of this fact. one person using the device may so grip thehandle 11 and lover, as to give complete control, and perform thenecessary manirtmlations on a valve of a dismantled nvlins withoutliability of tipping over thc latter.
